VEHICLE RADIO INTERFERENCE SENSOR DEVICE

An interference sensor device is disclosed. The interference sensor device includes a first conductive plate, a second conductive plate aligned parallel to the first conductive plate, a non-conductive matter between the first conductive plate and the second conductive plate wherein the first conductive plate is coupled to a first input of a first amplifier and the second conductive plate is coupled to a second input of the first amplifier, wherein an output of the first amplifier is coupled to a first of the two input ports or the signal adder. The interference sensor also includes a sensor coil having two ports each electrically coupled to a first input and a second input of a second amplifier, wherein an output of the second amplifier is coupled to a second of the two input ports of the signal adder.
